Simple Mediterranean Tuna Salad

Last summer my neighbor Maria brought over a bowl of this after returning from Greece, and I honest to goodness ate half of it standing at her kitchen counter. The way the bright lemon hits the briny olives and sweet tomatoes creates this incredible Mediterranean sunshine feeling, even on the gloomiest Tuesday. I have been obsessed ever since.

I made this for my sister when she was recovering from surgery and she texted me three days later asking for the recipe because it was the first thing that actually sounded good to eat. Something about the combination of protein and crisp vegetables just hits different when you need nourishment but nothing feels appealing.

Ingredients

• Tuna in olive oil: Trust me on this, the olive oil packed version makes such a difference in flavor and moisture compared to water packed
• Cherry tomatoes: Look for ones that feel heavy and have that slight give when you gently squeeze them
• English cucumber: These have thinner skins and fewer seeds, but regular cucumbers work fine too
• Red onion: Soaking the sliced onion in cold water for ten minutes takes away that harsh bite if you are sensitive to raw onion
• Roasted red peppers: Jarred ones are perfectly fine here, no need to roast your own unless you want to
• Fresh parsley: Flat leaf parsley has better flavor than curly, and it holds up beautifully in the salad
• Kalamata olives: These purple Greek gems have this incredible depth that regular black olives just cannot match
• Capers: Little bursts of briny brightness that tie everything together
• Extra virgin olive oil: Use the good stuff here since it is one of the main flavor components
• Fresh lemon juice: Roll the lemon on the counter before cutting to get the most juice out
• Garlic clove: Minced finely so you do not bite into big chunks
• Dried oregano: Mediterranean oregano has this floral, almost piney flavor that is perfect here

Instructions

Prep the tuna:

Drain the cans and flake the fish gently with a fork, leaving some nice chunks for texture

Chop your vegetables:

Keep the pieces relatively uniform so every bite gets a little bit of everything

Combine it all:

Add everything to your large bowl except the dressing ingredients

Whisk the dressing:

Shake or whisk until the oil and lemon juice emulsify into a creamy consistency

Dress the salad:

Pour over and toss gently so you do not break up the tuna too much

Taste and adjust:

Trust your palate here, maybe it needs more lemon or a pinch more salt

Let it rest:

Give it at least fifteen minutes before serving, or refrigerate for up to two hours

Save

This recipe became my go to for those nights when nobody wants to cook but we still want something that feels special and intentional. There is something about the combination of flavors that makes even a regular Tuesday dinner feel like a little vacation.

Make It Your Own

The beauty of this salad is how forgiving and adaptable it is. Sometimes I add fresh basil or mint instead of parsley for a different herbal note, or I will throw in some artichoke hearts if I have them in the pantry.

Serving Suggestions

While this is perfectly satisfying on its own, serving it over a bed of mixed greens or with some crusty bread makes it feel more substantial. A crisp white wine like Sauvignon Blanc or even a light rosé complements the bright flavors beautifully.

Perfect For Summer Days

This has become my absolute favorite dish to bring to potlucks and outdoor gatherings because it does not wilt like lettuce based salads and tastes just as good at room temperature as it does chilled.

• Double the recipe for larger groups because it disappears quickly
• Pack the dressing separately if you are transporting it somewhere
• Add a hard boiled egg on top if you want extra protein without any additional cooking

Save

Hope this brings a little Mediterranean sunshine to your table like it has to mine. Enjoy every bite.

Recipe FAQs

→ Can I make this ahead of time?

Yes, you can prepare this up to 2 hours in advance and refrigerate. The flavors actually meld together beautifully during this time. For longer storage, keep the dressing separate and toss just before serving.

→ What type of tuna works best?

Tuna packed in olive oil provides the best flavor and texture, but you can use water-packed tuna if preferred. Just drain well and consider adding a splash of olive oil to the dressing.

→ How can I add more substance?

Try adding a hard-boiled egg, serving over mixed greens, or pairing with crusty bread. You could also add cannellini beans or chickpeas for extra fiber and protein.

→ What herbs can I substitute?

Fresh basil or mint work wonderfully as alternatives to parsley, each bringing a slightly different aromatic profile. Dried herbs like basil or thyme can also work in a pinch.

→ How long does this keep?

Best enjoyed within 1-2 days when stored in an airtight container in the refrigerator. The vegetables may soften over time, so add fresh ones if serving later.
